脸部是人体最复杂的区域之一,而了解脸部的运动甚至更加复杂。能够将面部运动分解为关键形状以一起使用以形成表情,这不仅可以简化脸部,还可以让您在CG中重新创建这些形状,并为复杂的表情设置动画。在Digital Domain的面部建模者Derrick Sesson的为期5小时的教程中,您将学习面部混合形状建模的所有基础知识。
本工作坊假定您不具有混合形状的先验知识,并使用Autodesk Maya指导您完成整个面部处理。Derrick首先对FACS(面部动作编码系统)进行了详尽的解释,然后准备ZBrush头部进行变形,分解脸部每个区域所需的基本形状,并使用变形器(例如簇)阻止这些形状。他展示了如何使用Maya的雕刻工具优化这些形状,然后再将它们全部融合到blendshape节点中。
本工作坊中的概念和课程将使您对FACS以及如何创建混合形状有基本的了解,为您提供创建一组面部混合形状所需的所有技能,使您可以控制将脸部变形为任何表情喜欢。
在整个研讨会上展示的头部模型是由3dscanstore.com的才华横溢的团队创建的,可免费使用。教授的技能也可以应用于其他角色头像模型。

Info:
The face is one of the most complex areas of the human body, and understanding the motion of the face is even more complex. Being able to split facial motion into key shapes to be used together to form expressions not only simplifies the face but allows you to re-create these shapes in CG, and animate complex expressions. In this 5-hour workshop by Derrick Sesson, a Facial Modeler at Digital Domain, you will learn all the basics of Facial Blendshape Modeling.
This workshop assumes you have no prior knowledge of blendshapes, and takes you through the full facial process using Autodesk Maya. Derrick starts with a thorough explanation of FACS (Facial Action Coding System), before preparing a ZBrush head for deformation, breaking down essential shapes needed for each region of the face, and blocking in those shapes with deformers, such as clusters. He shows how to refine those shapes with Maya’s sculpting tools, before bringing them all together into a blendshape node.
The concepts and lessons in this workshop will equip you with a fundamental understanding of FACS and how to create blendshapes, providing you with all the skills you need to create a set of facial blendshapes that give you the control to morph a face into any expression you like.
The head model showcased throughout the workshop was created by the talented team at 3dscanstore.com and is available for free. The skills taught can also be applied to other character head models.
